SPECIFICATION forming part of Letters Patent N o. 632,337, datedSeptember 5, 1899.

Application filed June 22, 1899. Serial No. 721,448. (No model.)

To all whom, it may concern.-

Be it known that I, FRED CLARK, a citizen l of the United States,residing at lVaco, in the county of McLennan and State of Texas, haveinvented certain new and useful Improvements in Car-Vheels, of which thefollowing is a specification.

This invention relates to improved means for securing tires tolocomotive-wheels; and it has for its object to provide improvedtireattaching devices so constructed that the tires may be easily andquickly tightened up to compensate for expansion and elongation and tohold the tires securely in place under any amount of expansion thereofliable to occur in practice.

To these ends my invention consists in the features and in theconstruction, combination, and arrangement of parts hereinafterdescribed, and particularly pointed out in the claims following thedescription, reference being had to the accompanying drawings, forming apart of this speciiication, wherein- Figure l is a view in elevation ofa locomotive -wheel embodying my invention, and Fig. 2 is a verticaltransverse central section thereof.

Heretofore the tires of locomotive-wheelsl have been extremely apt toquickly become loose owing to expansion and elongation and to the greatweight and wear they are subjected to. By means of myinvention the tiresmay be quickly tightened and securely held in place on the wheels in thefollowing manner.

Referring to the drawings the numeral l indicates a locomotive-wheel ofordinary orv usual construction, and 2 the tire removably arrangedthereon. Formed in the rim 3 of the wheel at suitable distances apartare threaded perforations, into and through which are screwedmachine-screws 4, provided on their inner ends with square or angularheads 5,

adapted to be engaged by a wrench for turnloosely engage the slots orsockets in the tire the latter may have a certain amount of expansion(in practice at least one-half an inch) without injuring the screws andwithout being displaced from the wheel.

In order to eectually prevent any lateral displacement of the tirerelatively to the\ wheel, I provide a plurality of U-shaped metallicclips 7, that embrace the rim 3 of the wheel and are secured in place bythe screws 4, which pass through suitable perforations formed in saidclips. The ends of the clips also embrace the opposite sides of the tireand in order that they may lie flush with said sides I form recesses 8in the sides of the tire in which the ends of the clips are seated. Inthis manner the clips are prevented from projecting beyond the sides ofthe tire and cannot therefore strike or engage any part of thelocomotive.

Having `described my invention, what I claim isl. The combination with alocomotivewheel, of screws screwed through the rim thereof and providedon their inner ends with heads, and a tire disposed circumferentially onthe wheel and provided on its inner circumference with Unthreaded slotsor sockets into which theouter ends of the screws loosely project, andU-shaped clips embracing said wheel-rim and the sides of the tire andheld in place by the screws, substantially as described.

2.V The combination with a locomotivewheel, of screws screwed throughthe rim thereof and provided on their inner ends with heads, a tiredisposed circumferentially on the wheel and provided on its innercircumference with slots or sockets into which the outer ends of thescrews loosely project, and U -shaped clips embracing said wheel-rim andthe opposite sides of the tire, the ends of said clips being seated inrecesses formed .in the sides of the tire and said clips being held inplace by the said screws, substantially as described. l

vIn testimony whereof I affix my signature in presence of two witnesses.
